Rob Paulsen voiced Donatello in Nickelodeon’s 2012 Teenage Mutant Ninja Turtles series.
Paulsen is a prominent voice actor whose credits include many animated television characters. His connection to the franchise goes further: he had previously voiced Raphael in the 1987 Teenage Mutant Ninja Turtles series, making his casting as Donatello in the 2012 show a notable role change.
The 2012 series used a new principal voice cast for the four brothers. Sean Astin voiced Raphael, Greg Cipes voiced Michelangelo, and Jason Biggs initially voiced Leonardo before Seth Green took over the role. Donatello’s voice remained associated with Paulsen.
This casting detail is easy to mix up because Paulsen played a different turtle in the earlier cartoon. It is also separate from the actors who voiced Donatello in the 1990 film trilogy, the 2018 series Rise of the Teenage Mutant Ninja Turtles, and later animated productions.
